How to read the table. A domain score is a 0–100 composite of the indicators in that domain; higher values represent a higher mean of distress-oriented indicator percentiles. A county's domain rank is computed separately against all counties. Percentile is Tuolumne County's national rank among all 3,144 U.S. counties for that indicator, always oriented so higher = more distressed.

Methodology

The County Distress Index scores household financial distress from 0 to 100 for all 3,144 U.S. counties. A county's score is the share of U.S. counties it is more distressed than. The index is built from five equal-weighted domains: Delinquency, Default & Legal, Debt Burden, Labor, and Safety Net & Buffer. Each domain is the mean of distress-oriented indicator percentiles; the five domains are averaged, and that average is ranked against every other county to give the score.

Data sources include the Urban Institute Debt in America (Equifax consumer credit panel), Equifax data retrieved via FRED (subprime credit share), U.S. Census Bureau (American Community Survey 5-year, Small Area Income and Poverty Estimates), U.S. Bureau of Labor Statistics (Local Area Unemployment Statistics), Administrative Office of the U.S. Courts (F-5A bankruptcy filings), and U.S. Department of Housing and Urban Development Fair Market Rents. Data vintages range from 2024 to 2027 depending on source; full indicator-level vintage detail is in the methodology document.
